Abbas Mohammed

Abbas Mohammed is a Professor of Telecommunications Theory at the School of Engineering, Blekinge Institute of Technology (BTH), Sweden. He was awarded the PhD degree from Liverpool University, UK, in 1992 and the Swedish Docent degree in Radio Communications and Navigation from BTH in 2001. He is the recipient of the Blekinge Research Foundation Award "Researcher of the Year Award and Prize" for 2006. From 1993 to 1996, he was a Research Fellow with the Radio Navigation Group, University of Wales (Bangor), UK. From 1996 to 1998, he was with the University of Newcastle, UK, working on a European collaborative project within the ACTS (Advance Communications Technologies and Services) FP4 Research Programme that investigated 3G Satellite-UMTS systems. He was also employed by Ericsson AB, where he consulted on power control standardization issues for 3G mobile communication systems. He has been a visiting lecturer to several universities. He is a Fellow of The Institution of Electrical Engineering since 2004. In 2006 he received Fellowship of the UK's Royal Institute of Navigation "in recognition of his significant contribution in navigation and in particular to advanced signal processing techniques that have enhanced the capability of Loran-C". He is a Senior Member of IEEE and a Life Member of the International Loran Association, USA. He is the Editor-in-Chief of ACEEE International Journal on Communication (USA) and the Journal of Selected Areas in Telecommunications of Cyber journals (Canada). He is a Board Member of the IEEE Signal Processing Swedish Chapter since its inception in 2000, and the UK’s IET Teknologia Journal to promote the research from the Middle East/North Africa region. He is an Associate Editor to the International Journal of Navigation and Observation and the Mediterranean Journal of Electronics and Communications, and a former Editorial Board Member of the Radio Engineering Journal. He has also been a Guest Lead Editor for several special issues of international journals. He is the author of over 200 publications, including many invited articles in peer reviewed Journals special issues and over 25 book chapters, in the fields of telecommunications, navigation systems and signal processing. He has also developed techniques for measuring skywave delays in Loran-C receivers and received a Best Paper Award from the International Loran Association, USA, in connection to this work. He is the Swedish representative and member of the management committee to the European Community COST 280, 296, 297, IC0802, IC0902 and IC1102 Projects. From 2002-2010, he is the BTH Director of the Graduate School of Telecommunications (a collaborative consortium in research and education between 4 Swedish universities), chaired by the Royal Institute of Technology (KTH). Professor Mohammed's research interests are in space-time signal processing and MIMO systems, channel modelling, antennas and propagation, satellite and high altitude platform communications, cognitive radio and dynamic spectrum access, and radio navigation systems.
